含硒硫锑铅矿在我国的发现及其意义

DISCOVERY AND SIGNIFICANCE OF SELENIAN BOULANGERITE IN CHINA

含硒硫锑铅矿是硫锑铅矿的含硒变种，产于皖南宋冲锑－铅矿点的矿脉中，这是含硒硫锑铅矿在我国的首次发现。在该矿点，含硒硫锑铅矿含量高，独立形成锑－铅矿体，这在国内外尚属首例。含硒硫锑铅矿中Ｓｅ的含量ｗＳｅ＝１．５８８％，其化学式为（Ｐｂ４．６１７１Ａｇ０．０２１７）４．６３８８（Ｓｂ３．６７８１Ａｓ０．１９００）３．８６８１（Ｓ１０．６３４５Ｓｅ０．０３６３７Ｔｅ０．００１８））１１。

Selenian boulangerite,a selenian variety of boulangerite,occurs in the mineral veins at Songchong Sb-Pb deposit,South Anhui.It is the first discovery of selenian boulangerite in China.The deposit is also the first of its type that has ever been discovered in the world.Our research not only adds to the study of mineralogy,but also provides mineralogical data for prospection of Se and Te in South Anhui.
